Although he couldn't completely draw it out yet, after practicing day and night, the method of painting Formation Patterns was already second nature to him, and it wasn't long before he pointed out a few places to Master Chen:
"Indeed, it is a problem with the Formation. These Formation Patterns are worn out, the spiritual power cannot be transmitted, and so the Formation has failed."
